A cooler for cooling bulk material, in particular cement clinker, may include a cooling gas chamber through which a cooling gas flow for cooling the bulk material can flow in crosscurrent, and a conveying device for conveying the bulk material through the cooling gas chamber in a conveying direction. The cooling gas chamber may include a first cooling gas chamber portion with a first cooling gas flow and a second cooling gas chamber portion, adjoining the first cooling gas chamber portion in the conveying direction of the bulk material, with a second cooling gas stream. The cooler may include a separating apparatus for gastight separation of the cooling gas chamber portions from one another. The separating apparatus may have sealing element and at least one suspension element, to which a plurality of sealing elements are attached.

Cooler for cooling bulk material, in particular cement clinker

The invention relates to a multi-level furnace for thermal treatment of the material flow which has at least two process chambers arranged one above another, each providing at least two level floors, and is equipped with one or more transfer devices for transferring the treated material flow from an upper process chamber to a lower process chamber. In order to separate the two process chambers in terms of gas flow, the transfer device has means for forming a material column in the transition region between the upper and the lower process spaces, wherein said means for forming a material column comprise at least one conveying unit or at least one chute, and the at least one conveying unit or at least one chute also forms a material removal device for the upper process chamber and/or a material input device for the lower process chamber.

Multi-level furnace and method for thermal treatment of a material flow

The invention relates to a plant and to a method for the production of cement clinker from cement raw meal, the cement raw meal being preheated in a preheating zone, precalcined in a calcining zone, completely burned in a sintering combustion zone and cooled in a cooling zone, solid fuels additionally being burned in an additional combustion region, a firing region being used in the additional combustion region, the solid fuel being introduced into the firing region where it forms a fuel bed over which a supplied oxygen-containing gas flows, the resulting combustion products being removed via a discharge opening and being used in the production of cement clinker. The fuel is supplied via a conveyor device arranged outside the firing region, in such a manner that it moves the fuel bed that is present in the direction towards the discharge opening.

A device for drying and torrefaction of at least one carbon-containing material flow in a multiple-hearth furnace includes a drying zone, a torrefaction zone, a heat exchanger for heating the drying gas flow, the discharge point of the drying zone being connected via the heat exchanger to the infeed point of the drying zone; and a combustion assembly, wherein the discharge point of the torrefaction zone is connected via the combustion assembly and the heat exchanger to the infeed point of the torrefaction zone, wherein a torrefaction gas flow discharged via the discharge point of the torrefaction zone is combusted in the combustion assembly and the resulting exhaust gas is used in the heat exchanger to heat the drying gas flow and is fed to the torrefaction zone, wherein the drying zone and the torrefaction zone comprise two separate gas circulations.

The invention relates to an apparatus for treatment of material, especially for thermal and/or chemical treatment, having an ascending pipeline branch, a diversion chamber and at least one descending pipeline branch. In the diversion chamber there is provided a deflecting wall that is oriented substantially transversely to the direction of flow of the material entering the diversion chamber via the ascending pipeline branch.
